Fruiting body:
2-7cm tall, 0.1-0.4cm wide basally, widening upward to 0.3-1.8cm, simple, initially cylindric to nearly cylindric, then narrowly club-shaped to club-shaped, apex subacute, obtuse or broadly rounded, at times forked or lobed when mature, some nearly turbinate [top-shaped]; initially yellow-white to orange-white then gray-orange, finally pale brown, (apex forest green to dark green following a frost), staining irregularly brown or dark brown where cut or bruised (more conspicuously near base); smooth, becoming longitudinally rugose to rugulose [wrinkled to finely wrinkled], apex smooth becoming rugose, (Castellano), up to 7(15)cm, high, 0.3-1.5(3.5)cm wide, occasionally short-lobed at top, becoming clavate to somewhat ventricose [wider in middle], acute or obtuse; mustard yellow, light yellow or buff, then dull yellow to alutaceous, apex concolorous or greenish; rugose to rugulose to irregularly inflated, rarely perforate, (Corner(3)), 2-7cm high, 0.1-0.4cm wide basally, widening upwards to 0.3-1.8cm, simple, at first cylindric to subcylindric, then narrowly clavate to clavate, irregularly laterally compressed when mature, apex subacute, obtuse or broadly rounded, at times forked or lobed when mature, some nearly turbinate [top-shaped]; at first ''light yellow'' to ''pale yellow'', "cream buff", "pale ochraceous-buff" or "light buff", then ''greyish orange'' to ''flesh color'', "pinkish buff", "cinnamon buff", "clay color" or "cinnamon", finally ''caramel brown'' to ''brownish orange'', "tawny", "cacao brown", "walnut brown" or "pecan brown", (apex forest green to dark green following a frost, otherwise colored as the spore-bearing surface), staining slowly irregularly ''brown'' or ''dark brown'', "Mikado brown", "cameo brown" or "Verona brown" where cut or bruised, staining more conspicuously downward; smooth, becoming longitudinally rugose to rugulose, apex smooth becoming rugose, (Methven)

Flesh:
white to pale, slowly brown-orange when exposed, (Castellano), white, unchanging, (Corner(3)), at first solid, becoming soft and spongy upward as the apex enlarges; white to pallid, on exposure staining slowly irregularly ''brownish orange'', "cinnamon", "clay color" or "tawny", (Methven)

Stem:
base round in cross-section, at first ''yellowish white'' to ''orange-white'', "cartridge buff", "light buff", "light ochraceous-buff" or "light ochraceous-salmon", then ''greyish orange'' to ''flesh color'', "pinkish-buff", "cinnamon-buff", "pinkish cinnamon" or "cinnamon", finally ''light brown'', "tawny", "walnut brown" or "pecan brown", pubescent [downy] to tomentose; mycelial hyphae loosely interwoven or aggregated into rhizomorphic strands up to 0.1cm wide, binding the substrate, ''yellowish white'' to ''orange-white'', "cartridge buff", "light buff", or "pale ochraceous-buff", (Methven)

Chemical Reactions:
tissue dark green in FeCl3; no reaction in KOH (solution leaching to pale yellow or yellow), (Methven)

Odor:
not distinctive (Castellano, Methven)

Taste:
not distinctive (Castellano, Methven)

Microscopic:
spores 18-24 x 4-6 microns, narrowly elliptic, boletoid or sway-backed in profile, smooth, inamyloid, pale yellow in KOH, thin-walled, contents multiguttulate and refringent to aguttulate and amorphous; basidia (2-)4-spored, 65-105 x 8-12.5 microns, clavate, clamped, sterigmata 8-9.5 microns long; leptocystidia scattered and scarcely projecting, 50-70 x 2.5-5 microns, "cylindric to narrowly clavate, at times apically or subapically branched", walls thin and smooth, contents amorphous, pale yellow in KOH, clamp connections uninflated; hymenium extending over the apex of the fruitbody; subhymenium rudimentary; hyphae of trama 3-12 microns wide, "more or less parallel to longitudinally interwoven basally, more loosely interwoven upward, radially interwoven beneath the subhymenium, uninflated or inflated (-12 microns), branched", walls thin or irregularly thickened to 1 micron wide, smooth, contents amorphous, pale yellow in KOH, clamp connections uninflated or inflated (-12 microns), sometimes medallion or ampulliform; gloeoplerous hyphae 3-9.5 microns wide, "arising from generative hyphae at clamp connections, scattered throughout the trama, more abundant downward, uninflated, inflated (-14 microns) or strangulated, branched", walls thin and smooth, contents subopalescent, pale yellow in KOH, refractive under phase contrast, clamped, (Methven), spores (13)16-24(28) x 4-6 microns; basidia 60-115 x 8.5-13 microns, (Corner(3))

Spore Deposit:
"pinkish buff" (Petersen, using Ridgway color), ''yellowish white'' to ''pale orange'', "light buff", "pale ochraceous-buff" or "cartridge buff", (Methven)
